Question 2

SpaceX launched Israel's first moon lander, "Beresheet", from Florida It's total weight is;

Accepted Answer

Israel's first moon lander, the 585 kg "Beresheet" ("Genesis" in Hebrew), was launched atop a Falcon 9 rocket from the private US-based SpaceX in Florida, United States. At a cost of USD 100 million, it is the lowest-budget spacecraft to ever undertake such a mission. It is part of renewed global interest in the Moon, sometimes called the "Eighth Continent" of the Earth. The project is funded almost entirely by donations making it the first privately backed lunar lander mission.It was notably financed by businessman and philanthropist Morris Kahn. Other partners include Israel Aerospace Industries (IAI), Israel's space agency and Israel's Ministry of Science and Technology. Beresheet carries a "time capsule" loaded with digital files containing a Bible, children's drawings, Israeli songs, memories of a Holocaust survivor and the blue-and-white Israeli flag. Landing is the main mission, but the spacecraft also carries a scientific instrument to measure the lunar magnetic field, which will help understanding of the Moon's formation.

Question 3

In which asteroid Scientists found the evidence of abundant water-bearing minerals?

Accepted Answer

Scientists have discovered evidence of abundant water-bearing minerals on the surface of the near-earth asteroid Bennu. Data from NASA's OSIRIS-REx spacecraft that is currently orbiting the asteroid confirm the presence of aqueously altered, hydrated minerals on its surface.

Question 7

The researchers of this country developed a system that can produce electricity and hydrogen fuel from carbon dioxide.

Accepted Answer

Scientists from Ulsan National Institute of Science and Technology (UNIST) in South Korea have developed a system that can produce electricity and hydrogen fuel from carbon dioxide. The Hybrid Na-CO2 system can continuously produce electrical energy and hydrogen through efficient carbon dioxide (CO2) conversion with stable operation for over 1,000 hours. The key to this technology is the easy conversion of chemically stable CO2 molecules to other materials. Much of human CO2 emissions are absorbed by the ocean and turned into acidity. The researchers focused on this phenomenon and came up with the idea of melting CO2 into water to induce an electrochemical reaction.If acidity increases, the number of protons increases, which in turn increases the power to attract electrons. If a battery system is created based on this phenomenon, electricity can be produced by removing CO2. In particular, this system has shown stability to the point of operating for more than 1,000 hours without damage to electrodes. The system can be applied to remove CO2 by inducing voluntary chemical reactions.

Question 8

How many American astronauts are successfully replaced ageing batteries on ISS?

Accepted Answer

NASA's Anne McClain and Nick Hague took a spacewalk on 22nd March to replace ageing batteries on the International Space Station. Two American astronauts worked for several hours to swap three nickel-hydrogen batteries with more powerful lithium-ion ones. The duo overcame minor struggles in their first task, which involved attaching a tool bag on one of the station's trusses for possible future use. The space station uses solar panels to generate power but the batteries are used when it is in the dark and not getting power from the sun.

Question 9

Which spacecraft of NASA broke the record for smallest space object ever orbited, after successfully entering into orbit around the asteroid Bennu?

Accepted Answer

NASA's OSIRIS-REx spacecraft broke a record after successfully entering into orbit around the asteroid Bennu - the smallest cosmic object ever to be orbited by a spacecraft. NASA's OSIRIS-REx spacecraft, 110 million kilometers away, carried out a single, eight-second burn of its thrusters. The manoeuvre placed the spacecraft into orbit around the asteroid Bennu. The spacecraft will circle Bennu about 1.75 kilometres from its centre, closer than any other spacecraft has come to its celestial object of study.

Question 18

Name the new exotic planet discovered by researchers outside our solar system in the constellation Cassiopeia.

Accepted Answer

21 light years away on december 22, 2018 in the constellation Cassiopeia, a shimmering "super-Earth", five times the mass of Earth, dubbed as HD219134 b was discovered. Unlike the Earth, however, it most likely does not have a massive core of iron, but is rich in calcium and aluminium alongside magnesium and silicon. It shimmers red to blue like rubies and sapphires, because these gemstones are aluminium oxides which are common on the exoplanet. According to the researchers it is one of three candidates likely to belong to a new exotic class of exoplanets. The other two exoplanets studied were 55 Cancri e and WASP-47 e. The study was published in the journal Monthly Notices of the Royal Astronomical Society: Letters.

Accepted Answer

Indian Space Research Organisation's (ISRO) first mission of 2019, Microsat-R, is to be launched into space on 24th January 2019. The 130-kg Microsat-R is a military imaging satellite. Microsat-R and its payload come assembled from a handful of laboratories of the Defence Research and Development Organisation (DRDO) and is meant for military use. The satellite was assembled outside and ISRO only interfaced it with its own systems and the launch vehicle, just as it treats any customer satellite. PSLV-C44 will be launched from the older First Launch Pad at the Satish Dhawan Space Centre, Sriharikota in Andhra Pradesh. For its part, ISRO is experimenting on two aspects of the vehicle. One is to reuse a waste stage.
